Constriction is a method used by several snake species to kill or subdue their prey. Although some species of venomous and mildly venomous snakes do use constriction to subdue their prey, most snakes which use constriction lack venom. [ 1 ]
Rarely do individuals lack both the ventral and neck band coloration, so the use of those two characteristics is the simplest way to distinguish the species. [6] Size also varies across the species' distribution. Typically, adults measure 25–38 cm (10–15 in) in length, [6] except for D. p. regalis, which measures 38–46 cm (15–18 in). [7]
Rectilinear locomotion relies upon two opposing muscles, the costocutaneous inferior and superior, which are present on every rib and connect the ribs to the skin. [5] [6] Although it was originally believed that the ribs moved in a "walking" pattern during rectilinear movement, studies have shown that the ribs themselves do not move, only the muscles and the skin move to produce forward ...
This species is the only garter snake species with a well-documented tendency to constrict prey, although the constriction is inefficient when compared with the constriction of many other snakes (such as the gopher snake), involving disorganized, loose, and sometimes unstable coils and a longer time required to kill prey.
Since the diet of the bandy-bandy is specific to blind snakes, they are highly responsive to the chemical cues left by blind snakes. A study found that bandy-bandys were able to follow blind snake chemical trails for an average of 0.93 metres, while some specimens were able to follow the chemical trail to its completion, 1.4 metres long.

The brown-banded water snake grows to a maximum total length (including tail) of 78 cm (31 inches). Dorsally, it is olive or gray-brown, with dark brown, black-edged crossbands, which narrow at the sides, and are usually confluent with the black crossbands of the belly. There is a large dark rhomboid on the nape.
